Protege 4.0 Beta update (build 110)

Enhancements in Protege-OWL
---------------------------------
- A basic SWRL expression editor is now functional. Please be aware that
only RDF/XML is recommended for saving ontologies containing rules.

- Temp files are now used when saving files. If exceptions are thrown,
your original file will not be overwritten.

- Refactoring support for disjoints (pairwise <–> allDisjoint).

- Convert URIs to labels: new options allow the user control over where
annotations are placed.

Bug Fixes in Protege-OWL
----------------------------
- Change entity URI(s): does not work with entities containing escapes
in their URI.
